1. This heart condition is characterized by decreased cardiac output and tissue perfusion, which can lead to organ failure.

• A. Cardiogenic shock
• B. Myocardial infarction
• C. Endocarditis
• D. Pericarditis

Correct answer: A

Rationale: The correct answer is A: Cardiogenic shock. Cardiogenic shock is a severe condition characterized by the heart's inability to pump enough blood, leading to decreased cardiac output and tissue perfusion, which can result in organ failure. Choice B, Myocardial infarction, specifically refers to a blockage of blood flow to the heart muscle. Choices C and D, Endocarditis and Pericarditis, do not directly involve decreased cardiac output leading to organ failure, making them incorrect in the context of the symptoms described in the question.

2. The nurse is teaching a client about side effects of ACE inhibitors. What is the most important side effect to monitor?

• A. Cough
• B. Hyperkalemia
• C. Hypotension
• D. Dizziness

Correct answer: A

Rationale: The correct answer is A: Cough. ACE inhibitors commonly cause a persistent dry cough in patients. This side effect is important to monitor because it can indicate the development of angioedema, a serious adverse reaction that requires immediate medical attention. Hyperkalemia (choice B) is a potential side effect of ACE inhibitors but is not typically the most important one to monitor. Hypotension (choice C) and dizziness (choice D) are also possible side effects of ACE inhibitors, but they are not as critical to monitor as the development of a persistent cough.

3. Which medication relaxes the muscles around the airways, making it easier to breathe?

• A. Bronchodilator
• B. Corticosteroid
• C. Antihistamine
• D. Mucolytic

Correct answer: A

Rationale: The correct answer is A, Bronchodilator. Bronchodilators are medications that relax the muscles surrounding the airways, which helps to open them and makes breathing easier. Corticosteroids (choice B) work by reducing inflammation, antihistamines (choice C) are used to manage allergies, and mucolytics (choice D) help to break down and thin mucus in the airways.

4. What is a condition where the heart beats with an irregular or abnormal rhythm?

• A. Arrhythmia
• B. Hypertension
• C. Tachycardia
• D. Bradycardia

Correct answer: A

Rationale: Arrhythmia is the correct answer because it refers to an irregular or abnormal heart rhythm, which can cause the heart to beat too fast, too slow, or erratically. Hypertension (choice B) is high blood pressure and not directly related to irregular heart rhythm. Tachycardia (choice C) is a condition where the heart beats too quickly, not necessarily irregularly. Bradycardia (choice D) is a condition where the heart beats too slowly, not necessarily irregularly. Therefore, only arrhythmia (choice A) fits the description provided in the question.

5. This is a more accurate indicator of tissue perfusion. It represents the cardiac output in terms of liters per minute per square meter of body surface area. Its normal range is 2.4-4 L/min.

• A. Cardiac Index
• B. Stroke volume
• C. Ejection fraction
• D. Cardiac output

Correct answer: A

Rationale: The correct answer is A: Cardiac Index. Cardiac Index is a measure of cardiac output relative to body surface area, providing a more accurate assessment of tissue perfusion. It is calculated by dividing the cardiac output by the body surface area. The normal range for cardiac index is 2.4-4 L/min/m². Choice B, Stroke volume, refers to the amount of blood ejected by the heart in one contraction and is not adjusted for body surface area. Choice C, Ejection fraction, is the percentage of blood pumped out of the heart's ventricles with each contraction, not adjusted for body surface area. Choice D, Cardiac output, is the total volume of blood pumped by the heart per minute, without considering body surface area.
